Question Second monitor

That depends on what type of input your current monitor uses and what type of input the monitor you get can use.

Based on the images on the product page, if it is accurate, then your graphics card SHOULD have one HDMI port and three Displayport ports. So long as you get a monitor that accepts Displayport inputs, or if your current monitor is using Displayport then either Displayport or HDMI is fine for the second monitor, you should not have any problems. You cannot use a monitor that only accepts DVI or VGA inputs, but most modern monitors rarely use those much anymore anyhow so just be aware of what you are getting.

Also, so long as the second monitor isn't being used for gaming you can also use the onboard CPU graphics through the HDMI port on the back of your motherboard if you needed to as well. Technically, you could connect five displays to that system.
